"While the Apple hype machine and its fanatical followers would have you believe that Mac OS X 10.5 'Leopard' is a major upgrade to the company's venerable operating system, nothing could be further from the truth. Instead, Leopard is yet another evolutionary upgrade in a long line of evolutionary OS X upgrades, all of which date back to the original OS X release in 2001. But let me get one huge misunderstanding out of the way immediately: That's not a dig at Leopard at all. Indeed, if anything, Apple is in an enviable position: OS X is so solid, so secure, and so functionally excellent that it must be getting difficult figuring out how to massage another USD 129 out even the most ardent fans. Folks, Leopard is good stuff. But then that's been true of Mac OS X for quite a while now." Additionally, Apple acknowledges installation problems caused by Unsanity's APE, while others are complaining about problems with Java, or visual oddities. Additionally, there are hacks that restore the black dock triangles, opacify the menubar, and to enable Time Machine on Airport disks. Update: It appears the Leopard firewall has a dent in its armour.
